The 2025 Mid-Season Invitational was the tenth iteration of the Mid-Season Invitational (MSI), a Riot Games–organized tournament for League of Legends, a multiplayer online battle arena video game. The tournament was played in Vancouver, Canada from June 27 to July 12, 2025, and was Canada's first hosting of an international League of Legends competition. It was also the first edition of the tournament to feature the Fearless Draft format, and the first to be staged under the game's new competitive esports calendar since 2025.
